[Fester Chugabrew]

You are saying that natural selection is not predictive, right?

Not in a way that is more scientifically meaningful than saying one would "predict" a find of cheeseburgers at a McDonald's Restaurant.

You are not being clear. What is the relationship you see between

"natural selection" ... is merely an arbitrary way of explaining what has already taken place

and

"predict[ing]" a find of cheeseburgers at a McDonald's Restaurant?
